blood cell surface protein that is glycosylated by products of the I gene with alleles IA, IB and/or i. Homozygous hh individuals have the "Bombay phenotype" with blood type O regardless of their I gene alleles. The H and I genes are on different chromosomes. A female and male who both have blood type O have three children. One of these children has blood type A and the other two have blood type B. Are these surprising blood types of the children best explained by dominance, complementation, or epistasis? What genotypes could the parents have to produce this outcome (indicate genotypes of both parents for both genes)? Be sure to answer both questions.

As described in a Codon Learning problem, alleles of the gene (dominant H, and recessive h) impact blood ABO blood types. The H gene encodes the red blood cell surface protein that is glycosylated by products of the I gene with alleles IA, IB and/or i. Homozygous hh individuals have the "Bombay phenotype" with blood type O regardless of their I gene alleles. The H and I genes are on different chromosomes. A female and male who both have blood type O have three children. One of these children has blood type A and the other two have blood type B. Are these surprising blood types of the children best explained by dominance, complementation, or epistasis? What genotypes could the parents have to produce this outcome (indicate genotypes of both parents for both genes)? Be sure to answer both questions.
